Google sponsored link in yellow box

So sometimes when you do a search you have 2 - 3 sponsored links a yellow box displaying first. You also have sponsored links on the right side of the page.

Being curious I set up an AdWords account and can easily place an add in the right column, no problem. What I am looking to do is get my add in the yellow box on the top left of the page, above the search results.

Anyone familiar with this?

Also, I couldn’t for the life of find how much it actually costs when someone clicks through to your site! haha
